) This PR adds comprehensive test coverage to ensure analyzers properly respect user disable configurations and don't generate false warnings when explicitly disabled. ## What's Changed Created `DisabledAnalyzerTests.cs` with test cases covering all major analyzer disable mechanisms: ### Pragma Warning Directives ```csharp #pragma warning disable Moq1200 new Mock<SampleClass>().Setup(x => x.Property); // No warning expected #pragma warning restore Moq1200 ``` ### SuppressMessage Attributes ```csharp [SuppressMessage("Moq", "Moq1200:Setup should be used only for overridable members")] private void Test() { /* ... */ } ``` ### Configuration-Based Disabling ```ini # .editorconfig [*.cs] dotnet_diagnostic.Moq1200.severity = none ``` ### Assembly-Level Suppression ```csharp [assembly: SuppressMessage("Moq", "Moq1200:Setup should be used only for overridable members")] ``` ## Test Coverage - **Multiple analyzer types**: Tests both `SetupShouldBeUsedOnlyForOverridableMembersAnalyzer` (Moq1200) and `NoSealedClassMocksAnalyzer` (Moq1000) - **Control tests**: Verifies analyzers still report diagnostics when NOT disabled - **Real-world scenarios**: Covers common patterns users employ to disable analyzers ## Performance Optimization Addresses the performance requirement from the issue - when analyzers are disabled via configuration (`severity = none`), the Roslyn framework automatically avoids calling the analyzer's analysis methods entirely, providing optimal performance by preventing unnecessary work before any registration occurs. ## Implementation Details - Uses existing test infrastructure patterns for consistency - Leverages `Microsoft.CodeAnalysis.Testing` framework - Tests work with both old and new Moq reference assemblies - No changes to analyzer code required - relies on framework-level disable handling This ensures users can reliably disable analyzers without receiving false warnings, improving the developer experience when customizing analyzer behavior for their projects.
